I have a 2012 base cayenne, 3.6 l. V-6, and I ordered a new oil filter housing because the drain plug not mine won't come out, someone stripped the hexadecimal socket. I got one with a plastic "tower" in the middle that the filter slides onto, but mine doesn't have that tower, plus the threads on mine are obviously different from the one I received. Every parts place I look up shows this housing with the tower, so I can't find the correct one. Anyone have experience with this? I've yet to visit my dealer but I probably will, although his price will likely be much higher than online pricing.
